SAMUEL N KNIGHT, OF SUTTER GREEK, CALIFORNIA.

HYDRAULIC ENclNE..

SPECIFICATION forming part of Letters Patent No. 314,689, dated March 3l, 1885.

(No modcLl T0 all whom, t 'nm/y colwernl.-

Be it known that I, SAMUEL N. KNIGHT, of the town of Sutter Creek, in the county of Amador and State of California, have invented an Improvement in Hydraulic Engines; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to engines by which pumps or other reciprocating apparatus may be driven.

It consists in the combination of devices hereinafter described and claimed.

Figure l, Sheet 1, is a side elevation of my machine. Fig. 2, Sheet 2, is a plan view of the same. Fig. 3, Sheet 8, is a transverse section of the main cylinder, showing also a section of the main and supplemental valvechambers and the supplemental cylinder for driving the main valve.

A is the main cylinder,within which the piston is iitted to reciprocate, having pistonrod B extending out from a suitable stuffingbox and connecting with the pump-piston or other apparatus to be driven.

C C are valve-chambers situated, as shown in the present case, above the cylinder Aand e having ordinary slide-valves,D,iitted to travel upon seats within the valve-chambers and alternately open to admit water through the ports E at opposite ends of the cylinder, and then to discharge or exhaust the water after its Work is done through the exhaust-passages F. These valve-chambers are arranged transversely across the ends of the cylinder A, and are supplied with water through the pipe or trunk G. The stems H of the valves D extend out through stufiingboxes in the ends of the valve-chambers, and the opposite ends of these rods connect with pistons within cylinders I, so that when these pistons are reciprocated within the cylinder the valves D will be moved to alternately admit and discharge water, las before described.

out through stuffing-boxes and lconnect with bars O, which move in guides upon the tops of the valve-chest C. These bars move at right angles with the main piston. P is a rod extending through guides above and parallel with the main piston-rod B, and It It are col lars which are secured to the rod P at any desired points by set-screws. An upright arm, Q, is fixed to the main pistonrod B so as to be moved with it, and its upper end is constructed so as to alternately come in contact with the collars R as the piston finishes its stroke toward the other end, and thus move rod P backward and forward a short distance and in line parallel with the movement of the main piston. The portion P of this rod, which passes above the valve-chest C, is preferably made rectangular in shape, and has fixed to it the inclined plates S in such a position that they will reciprocate beneath the bars O. These bars have anti-frictional rollers journaled upon vertical pins projecting downward from the bars, so that the inclines S will pass between these rollers T. It will be seen that,when the rod P is caused to reciprocate, carrying with, it the inclined or diagonal plates S, with these plates acting upon the rollers T or the bars 0, the valverods N and their attached valves K will be caused to reciprocateso that water may ble admitted into the cylinder I to move the inain valves D. Water is supplied to the valvechambers .I by pipes U, which extend from the main trunk G to the valve-chambers .Las shown.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent, is-

1. Ahydraulic engine having a main cylinder,piston,and piston-rod,transversely-placed valve-chambers at the ends ofthe cylinder Acontaining valves, and supplemental cylinders and pistons, valve-stems having rollers attached, and valves by which water is admitted to and exhausted from these cylinders, in combination with arm Q on the piston B, and the inclined plates S, adapted to move the valve-stems of the supplemental cylinder transversely to their own motion, as herein described.

2. A hydraulic engine having a main cylinder, piston, and piston-rod, valve-chambers ICO movement will aotuate the rod P, inclined I In witness whereof l have hereunto set my plates S, xed to the rod P and moving in hand.

slots or between rollers which are mounted upon the supplemental Valve-stems O, so that S' N' KNIGHT' the movement of the rod P will actuate these Witnesses:

Valves and move the stems at right angles S. H. NOURsE,

with its own motion. H. C. LEE.
